A feminist,[10] she said in her maiden speech, that the Palace of Westminster dated from "a time when my class and my sex would have been denied a place in it, because we are deemed unworthy".[11] Her speech was well-received by many and shared over 200,000 times on social media.[12] On 12 January 2018, she was appointed Shadow Minister for Business, Energy and Industrial Strategy.[13]

She has been a fierce critic of the lack of proxy voting in Parliament after being forced to attend a vote in 2018 when heavily pregnant.[14]

Pidcock is a strong critic of the incumbent Conservative government. She attracted attention in mid-2017 for calling them "the enemy" and saying she was "disgusted at the way they’re running this country".[15] Pidcock has also stated she has "absolutely no intention of being friends with any Tories."[16]

She maintains the government is doing far too little for poor people, and that her constituency has suffered long-term deindustrialisation and a lack of investment, leading to significant financial difficulties for many residents. She has highlighted the rise in volunteer organisations to help support people who she feels have been left behind by the state.[17]

On Universal Credit, Pidcock condemned the rollout just before Christmas when poor people's budgets are very tight. She asked, ‘My question for the Prime Minister is this. Is the roll-out a matter of gross incompetence or calculated cruelty?’[18]

In June 2017, Pidcock raised the issue of social housing saying she would accept a council house, but there were none available and was renting in the private sector. She was unable to afford the deposit for her first home, despite her MP's salary, because of university debt.[19]

Pidcock identifies as a socialist, and supports the policies of party leader Jeremy Corbyn.[20] She supports Britain leaving the European Union; her constituency voted strongly to leave and she said after her election that, “people were suffering even within that structure... Why would anybody vote for things to stay the same when their life is crap? Or it feels crap?”.[5] She has been tipped as a future party leader, though she has said she is more interested in grass-root politics.[5] She socialises little with MPs and has famously said that “she could never be friends with a Tory”.[21]
